To quote (via pastie.org/private/emwfwuoizwvq8tlirp6a): PROCEDURE CFW CREATION IS MIRALATIJERA same as CEX, we use DELTA PATCHER and the original file chose the PS3UPDAT.430.001 ORIGINAL AND THE PATCH THE FILE ATTACHED you create an installable ANY cfw 4.30 dex without bricking.
deleted lv1ldr protection against consoles converted "unofficially"
Finally, from Cyberskunk: First, nice job Miralatijera. Second, It is true 4.30 REX has been ready for a few weeks now and it does use a patched 430 lv1ldr instead of the 421 lv1ldr that does not have the check. I read a single sentence on ps3 dev wiki that stated there was a check in lv1ldr with no other details about it.. so i had a look.. found it.. patched it.. Job done. So guess i would have to give credit to the person that shared that snippet of info to work from.. Thanks

This seems awesome, and getting better all the time! Anyone have otherOS++ working on this? I may finally try otherOS now that this simplifies the process so much. The holy grail for me would be getting YDL 6 running on cfw 4.31, but don't think anyone has accomplished that. Guess i'll try red ribbon. After installing this MT cfw, I should be able to downgrade back to 3.15 ofw anytime through recovery mode with no problem, correct?
